I used to replace defective relay in Nutone 450 old relay board used 1 relay for both motors new board appears to have 2 relays 1 for each motor, this is my second relay failure, I think this unit with 2 relays should be much moe reliable.
Only problem I had was new female disconnects were 316 inch and motor disconnects were 14 inch I changed motor connections to 316 if I was sure the new unit was going to function correctly I would have changed new relay connections to 14 inch.
So far I am very happy with new circuit board.

Simple replacement and worked great. This board was not a direct replacement for my unit so be advised it may require some rewiring and drilling as mine did, but worked as well as the original once installed and at a fraction of the price of the oem replacement.
Ask a Question
Correct, this board is not grounded and not required to be grounded under its regulatory procedure.
Our circuit boards are not brand specific and may require modifications to the unit (such as drilling an additional hole) for proper mounting. The electronics on the board itself are the same (relay, transformer, mini breaker).
